I don't know what to tell you. We can both cherry pick defensive stats back and forth all day. The Jets are hanging around 16th in Points per game allowed and 20th in 3rd down conversions allowed, two pretty important defensive metrics to winning.
I'm looking at the body of work, including team success, W-L record, how the team responds, the stupid shit he says in pressers, has the team given up (last night would indicate a resounding YES), et al.
We can disagree, I'm cool with that. I don't think he knows what he's doing as an HC, and honestly I wasn't sold on his record as a DC in SF, considering the litany of 1st round talent he had to work with. He was a quota hire, and there's nothing wrong with that. I just don't think it's working.
